According to The Mirror, the happy couple is most certainly engaged. "The pair decided to take things to the next level and Madden popped the question with a diamond-encrusted ring," a source reportedly told Australia's Daily Telegraph.

While Diaz has been spotted several times wearing a statement-making gold-and-diamond bauble on a very specific finger, there have also been multiple occasions where she's stepped out sans the alleged engagement ring. The same of jewelry has also appeared on her right hand rather than her left before.

Without confirmation from their reps (or a close-up shot of that ring!) it's hard to say exactly what is going on with these two. But the one thing we know for sure? Their relatively short relationship (the pair has only been together since April) is built on a strong foundation. And marriage definitely isn't out of the question, either. In September Madden told Details that a family is "what every man wants, whether they admit it or not."

Whether or not they're actually engaged, we're holding out hope that these two are making plans to settle down for good!
